    The equations were developed with data from three long-term (greater than or equal to 10 years of record) continuous-record streamflow-gaging stations, 23 partial-record streamflow- gaging stations, and 5 short-term (less than 10 years of record) continuous-record streamflow-gaging stations. WREG is a desktop application that is used to develop a regional estimation equation for streamflow characteristics (e.g., low flow values). Users can apply these estimates at ungaged basins, or use them to improve the corresponding estimate at continuous-record streamflow gages with short records. The.

    This report presents the annual and monthly minimum 1- and 7-day average streamflows with the year recurrence interval (1Q10 and 7Q10) for continuous-record streamgages in Georgia. Streamgages used in the study included active and discontinued stations having a minimum of 10 complete climatic years of record as of Septem The 1Q10 and 7Q10 flow statistics were computed for.

Section A of Book 3 is on surface water. The unit of publication, the Chapter, is limited to a narrow field of subject matter.

This format permits flexibility in revision and publication as the need arises. Chapter Al3 deals with the computation of continuous records of stream-flow.

Records of continuous streamflow, published in the U.S. Geological Survey annual Water Data Reports for the States and territories, are computed from field data, mainly discharge measurements and recorder charts or tapes. This manual describes the computation procedures used and some details of related field operations.

The continuous record of stage is converted to streamflow by applying a mathematical rating curve.

A rating curve (fig. 3) is a graphic representation of the relation between stage and streamflow for a given river or stream.

1. INTRODUCTION 3 The streamflow records referred to above are primarily continuous records of discharge at stream-gaging stations, a gaging station being a stream-site installation so instrumented and operated that a con-tinuous record of. Computation of Continuous Records of streamflow Continuous records can be computed from point discharge measurements and corresponding sensors deployed at gaging stations.

Data quality of stream flow records will vary depending upon the level of care and precision taken during the measurement of parameters, as well as site conditions at the. The record-approval process must include review by a hydrographer experienced in developing and applying suspended-sediment-surrogate regression models.

As with streamflow and continuous water-quality records, the characteristics of the model and important results from the record-computation process must be summarized in a station analysis.

Until the advent of ADCPs, it was difficult or impractical to accurately compute streamflow records on tidally affected rivers or rivers affected by backwater.

Streamflow Record Computation using ADVM's and Index-velocity Methods This 5-day class will provide an introduction to the use of acoustic Doppler velocity meters (ADVM's) for computation of continuous records of streamflow.

The USGS annually publishes the record from each streamflow-gaging station as mean daily discharge values and provides real-time discharge data from more than 4, streamflow.Continuous simulation of streamflow is useful for predicting the impacts of land-use changes and stormwater management practices on stream stability and ecology.

The shear stress-duration curves needed for stream stability studies are readily generated from simulated streamflow records.
